我想计算表格中每个商品编号的出现次数。我的表格结构如下:
|customerNumber|OrderNumber|ArticleNumber|
|1|1|1|
|2|2|2|
|3|3|4|
|1|4|3|
|3|3|2|
|4|5|2|
|5|6|4|
预期结果:
|ArticleNumber|NumberOfOrders|
|1|1|
|2|3|
|3|1|
|4|2|
我该怎么办? (我不知道atm)

您可以使用tablename
语法select ArticleNumber,count(NumberOfOrders) as NumberOfOrders from
tableName group by ArticleNumber
来满足您的要求。
现在,代码可以是,
.custom_chk input[type="checkbox"] {
display: none;
}
.custom_chk label {
border: 1px solid #e9f8fb;
padding: 16px;
display: block;
position: relative;
cursor: pointer;
-webkit-box-shadow: 1px 2px 3px -2px #999;
-moz-box-shadow: 1px 2px 3px -2px #999;
box-shadow: 1px 2px 3px -2px #999;
margin-top: 15px;
margin-bottom:10px;
background: #FDFDFD;
font-family: 'proxima_novaregular', Gotham, "Helvetica Neue", Helvetica, Arial, "sans-serif";
font-weight: normal;
}
.custom_chk label::before {
background-color: white;
border: 1px solid #ff6d6d;
color: white;
content: " ";
display: block;
height: 25px;
line-height: 28px;
position: absolute;
right: -2px;
text-align: center;
top: -2px;
transform: scale(0);
transition-duration: 0s;
width: 25px;
}
.custom_chk :checked+label {
outline: 2px solid #FF6D6D;
}
.custom_chk :checked+label:before {
content: "\2713";
background-color: #FF6D6D;
transform: scale(0.9);
}
